using both tracert & ping, get responses until it reaches ip4.gtt.net [69.174.5.42] Request timed out.

This appeared around the time of the shopping cart error and have not been able to use home IP for your website.

as stated elsewhere, any other PC, phone, Tablet, using various browsers works fine. No matter what I try, and confirmed by my ISP, the home IP I connect from is blocked by the ip4 server handling kelestia.com yet all other internet websites work fine :/

I have no trouble from any other IP address.
I even went as far as double checking all cache, cookies, history, firewall, router/modem settings which took 3 days to dig through everything.

That is when I contacted my ISP, who then used my IP to confirm it's blocked and not a setting or issue on my side.

It seems your DNS/name provider is blocking me when it double check connection via you domain server to your website
